Over the past decades, the development of high performance lightweight polymer nanocomposites and, in particular, of epoxy nanocomposites has become one the greatest challenges in material science. The ultimate goal of epoxy nanocomposites is to extrapolate the exceptional intrinsic properties of the nanoparticles to the bulk matrix. However, in spite of the efforts, this objective is still to be attained at commercially attractive scales. Key aspects to achieve this are ultimately the full understanding of network structure, the dispersion degree of the nanoparticles, the interfacial adhesion at the phase boundaries and the control of the localization and orientation of the nanoparticles in the epoxy system. In this Personal Account, we critically discuss the state of the art and evaluate the strategies to overcome these barriers.

Carbon nanomaterials with a different character of the chemical bond—graphene (sp2) and nanodiamond (sp3)—are the building bricks for a new class of all-carbon hybrid nanomaterials, where the two different carbon networks with sp3 and sp2 hybridization coexist, interacting and even transforming into one another. The extraordinary physiochemical properties defined by the unique electronic band structure of the two border nanoallotropes ensure the immense application potential and versatility of these all-carbon nanomaterials. The review summarizes the status quo of sp2 – sp3 nanomaterials, including graphene/graphene-oxide—nanodiamond composites and hybrids, graphene/graphene-oxide—diamond heterojunctions, and other sp2–sp3 nanocarbon hybrids for sensing, electronic, and other emergent applications. Novel sp2–sp3 transitional nanocarbon phases and architectures are also discussed. Furthermore, the two-way sp2 (graphene) to sp3 (diamond surface and nanodiamond) transformations at the nanoscale, essential for innovative fabrication, and stability and chemical reactivity assessment are discussed based on extensive theoretical, computational and experimental studies.

“…Jiang et al, [11] developed Composites of epoxy/graphene modified diamond filler f thermal conductivity and high electrical insulation. Performance of the epoxy was improved by incorporating diamond microparticles that were covered with few-layer graphene sheets on surfaces it not only improved dispersion of diamond in the polymer matrix but it also decreased the interfacial thermal resistance between the diamond and Epoxy while preserving an excellent electrical insulation.…”

Composite materials especially the polymer matrix materials are well acknowledged for their applications in aerospace, automotive and structural applications. They are considerably light weight and offers high strength weight ratio. Epoxy is one of the widely used matrix material in PMCs (Polymer matrix composite) due to its exceptional bonding capabilities, it finds applications in the field of coating, adhesives and composite materials. Graphene is a novel material in the field of composite materials it offers high strength, very high electrical conduction and heat tr composites of Epoxy and Graphene hybrids exhibit very high mechanical and thermal properties.
